Improvement in horse-powers



UNITED? STATES I uvIPRo'vEMl-:N'rm .HoRsE-Powens specification forming pm or Letters Patent No.' 36.575, dated september 3o, 1862.

To all whom, it may concern.:

Be it known that we, JOHN S. ROWELL and MICHAEL F. LOWTH, both of Beaver Dam, in the county of Dodge and State of Wisconsin,

have invented a new and useful Improvement in Horse-Powers; and we do hereby declare the following to be av full and exact descrip-|- -tion of the' saine, reference being had to the accompanying drawing, makingpart 'of this specification, and being a perspective-.view of a horse-power illustrating our invention. l

Our improvement relates to 'that classof horse-powers in which a horizontal master-4 wheel -is made toact upon two pinions secured to a tumbling-shaft which extends the whole length'of the power; and the invention particularly consists in an improved arrangement of parts, whereby `the friction upon the bearings is reduced, and the wheels caused to continue to work well in gear after having become somewhat worn. l'Io enable others skilled in the art to which our invention appertains to fully understand and use the same, we will proceed to describe its construction and operation.

A is the stationary frame-or bed. B is the mastenwheel or main driving wheel to which the sweeps are attached.' The said'masterwl i eel is provided on'its under face, near its circumference, with 'bevelcogs b, which take into pinions C lC upon short horizontal shafts D D', running in bearings E E. The

shaft D carries Iat its outer end a -cog-wheel,

F, and the shaft D an internalgear wheel, G.'

- H is a tumbling-shaft extending from end to end of the power,y and as far in one direction as may be needful for the attachment of the band-pulley or other means of communieatingl motion to the machinery to be driven.

The said tumblingshaft runs in bearings h h,

and is provided with pinions I and I', Iwhich gearwith the wheels F and G, respectively.

J J are clips secured to the main frame A,

and eng ging ove, the irnaster-whee rit in gear withthe piuions C C'.

`. InA the drawing-a portion of the master- `wheel is represented as broken away, in order vto show the partsbeneath. It will be observed that as the master-wheel `is caused 'to revolve in the direction ofthe ar-v 1 B to heid row the lateral pressure thereby exerted upon, vfthe shafts D D through the'pinions C Cnwill" ",draw both theyvhecls F G rmly,.into gear z with the piions I'and l', and as resistance `is applied to the shaft1 H the pressure, beingin the opposite direction, will in a great degree equalize and reduce the friction upon the bearings. VIn like manner the pressure upon-opposite sides of the tumbling-shaft equalizes ang reduces the friction in the bearings h.

s the bearings and gears wear away, the Wheels F and G are still drawn, into contact with their pinions, and the machine thus caused to operate with unimpaired effect.

VThis invention entirely dispenses with the necessity for friction-rollers, which, with horse- 4powers having bevel-gears running' at a high speed, are usually-reqaired to hold the said' wheelsin gear.

We do not Vclaim the invention of a tumbling-shaft driven by two bevelv orhorizontal gear-wheels and pinions; but,v

Havmgthus described our invention, what 'we claim as new therein, Iand desire to secure.
